摘要： The invention relates to a method and a device for driving an LED string of a first LED segment (11) and at least one further LED segment (12, 13, 14) connected in series. Each LED segment has at least one light emitting diode, LED. The LED string is powered by a rectified AC mains voltage. The first LED segment (11) is powered when the rectified AC mains voltage is above a first voltage level, and the first LED segment and the further LED segment are powered when the rectified AC mains voltage is above a second voltage level higher than the first voltage level. The first LED segment emits light having a first color temperature, and the further LED segment emits light having a second color temperature higher than the first color temperature. The light emitted by the first LED segment and the light emitted by the further LED segment are superimposed. The color temperature change of the light emitted by the LED string, when dimmed, resembles the color temperature change of an incandescent lamp.

摘要： A series arrangement of LED loads (LP1-LP4) is coupled between output terminals of a rectifier having its input terminals coupled to a mains supply supplying a low frequency AC voltage. Control means render the LED loads conductive one by one, when the amplitude of the supply voltage increases, and non-conductive one by one when the amplitude of the supply voltage decreases. The first LED load (LP1, LP2) has a forward voltage that is substantially higher than that of the other LED loads. As a consequence, the LED utilization is comparatively high, thus allowing the LED loads used in the series arrangement to be comparatively cheap.
摘要翻译： LED负载（LP1-LP4）的串联布置耦合在整流器的输出端子之间，其输入端子耦合到提供低频AC电压的电源。当电源电压的幅度增加时，控制装置使LED负载一个接一个，当电源电压的幅度减小时，LED逐一导通。第一个LED负载（LP1，LP2）具有远高于其他LED负载的正向电压。因此，LED利用率相对较高，从而允许串联装置中使用的LED负载相当便宜。

摘要： LED light source comprising a string of LED loads (LED1-LED4) supplied by a rectified mains voltage. The number of LED loads carrying current is increased as the momentary amplitude of the rectified mains voltage increases, and is decreased as the momentary amplitude of the rectified mains voltage decreases. The order in which the LED loads start carrying a current and the order in which the LED loads stop carrying a current is reversed for each half period of the mains.

摘要： The invention relates to a valve for opening and closing a channel (3) of a microfluidic system, respectively. According to the invention, the valve comprises an actuation medium (2) that undergoes a volume change with changing temperature; and a heater arrangement (5) for generating a temperature gradient in the actuation medium (2) with respect to the actuation medium's (2) distance relative to the channel (3); wherein due to an expansion or a contraction of the actuation medium (2) the channel (3) is closed or opened, respectively. When the heater arrangement (5) is activated in such a way that a higher temperature is generated in the actuation medium (2) which is nearer to the channel (3) and a lower temperature is generated in the actuation medium (2) which is further away from the channel (3) the valve can be closed and vice versa. Accordingly, such a valve for a microfluidic system is provided which can be reliably actuated during a long time of use.

摘要： The invention relates to a transducer device (100,200,300,400) for detecting an environmental state or a change in the environmental state, in particular for detecting an environmental state within a biological material. The transducer device (100,200,300,400) comprises a channel (2,22,51) comprising a fluid, a hydrogel material (1,21,51), which is adapted to change its volume when getting into contact with an environmental material and/or when detecting an environmental change, and which is mechanically coupled to the channel (2,22,51) such that the volume of the channel (2,22,51) changes when the volume of the hydrogel material (1,21,51) changes. The transducer device (100,200,300,400) further comprises a sensor (11,12,25,35), which is adapted to generate a signal upon detection of the change of a physical property of the fluid that is induced by the volume change of the channel (2,22,51). By applying the transducer device (100,200,300,400) according to the invention within a bodily lumen, an accurate monitoring of physiological parameters, for which the hydrogel material (1,21,51) is sensitive, within the bodily lumen is possible. It is also possible to apply the transducer device (100,200,300,400) outside of the bodily lumen, for example to monitor the blood of a patient outside the bodily lumen.
